    摘要: Tocopherol derivatives having the general formula: wherein n is an integer of 6 to 13, R1 is hydrogen, a silyl ether or acetate, R2 is an optionally substituted nitrogen-containing heterocycle or a polycyclic nitrogen-containing heterocycle; and pharmaceutically acceptable salts thereof are provided. A method for synthesizing the compounds is also provided. The tocopherol derivatives are capable of inhibiting the primary enzyme responsible for the metabolism of the tocopherols and tocotrienols compounds of vitamin E, namely tocopherol-ω-hydroxylase, and thus increase the amount and prolong the availability of these compounds in plasma and tissue.

    摘要: The present invention is a method for measurement of moisture in dielectric materials. It is particularly useful for lumber. In the preferred version, at least two alternating current signals whose frequencies differ by a factor of at least 10 are capacitively coupled to the material. The coupling electrodes are in bridge circuits whose unbalance is measured at each frequency. The temperature of the dielectric material is also determined. Bridge unbalance signals are separated and rectified and the voltages, as well as a temperature analog voltage, are entered into a microprocessor programmed with a suitable algorithm to calculate a temperature corrected moisture value. The method overcomes significant inaccuracies in moisture readings due to temperature dependency.
